Application filed April 5, 1

' others skilled in the art to which it appertains-to make I and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereonv forming part of this specification.

My invention relates to pneumatic tires, and has for its objects the construction of a tilted pneumatic tire sheath,.and the wheel rim'therefor, in such a manner that the tire-sheath can be securely fastened to the riin'f so as to effectually prevent its creeping thereon, and

can readily be'removed therefrom to admit of the remove! and insertion of the innertube. In accomplishing this result I make the tire-sheath of the usual shape, having an open rift in the inner face thereof, and with the edges of the riit-non-extensible, and one edge of greater annular circumference than the other, so that one edge of the rift will rest on theperiphery of the inetal'tire on the wheeluim, whilethe' other extends down into recess formed by the cutting away of the edge of the metal tire, where pointed studs are provided which are pressed into the fabric of the sheath by the flanges bolted to the sides of the wheel-rim in the usual mannerv panying drawings in which Figure l is a. transversesection of a' \vheel'rini and pneumatic tire embodying my invention. Fig.2 is a like view shov. ing a' modified construction of the same.

In these draw ings A is a pneumatic tire-sheath having a rift or opening B in its inner face. The edge 0 of p Specification of Latte 5 Patent.

The features of this invention are hereinafter fully, set forth and explained, and illustrated inthe accom 'extensible and one edge of the rift of greater PatentedNovv 5, 1902:.

extensible, preferably by vulcanizing non-extensible rings 0 therein, as illustrated in Fig. 1, or byvulcanisn ing straight strips of fabric t therein as illustrated in Fig. 2. i I

To prevent creeping orrotation of the sheath A upon the metal tire D, I preferably secure, at suitable'intervals, pointed studs d in the edge of the inetal tire D, as

illustrated in Fig. l, or in lieuthereof, like pointedstuds f in the flange F which secures that side of the sheath in place, as illustrated in F ig.2. 1

The flanges F and F for securing the sheath A. to the Wheel-rim are of the usual construction and are secured to the Wheel-rirn by bolts f and nuts f in the usual manner. The inner-tube G is of the usual construction used in pneumatic tires.

When it is desired to remove the inner tube G from the'sheath A, or to remove both the inner-tube and sheath from the Wheel-rim D, the inner-tube is first defiated, the nuts f on the bolts. f are then removed andthe flange F detached from the wheel ielly. "he edge G of the sheath A can then be moved outward and the inner-tube G removed therefrom and repaired and re placed in the sheath A, or if desired the sheath A can then be removed from the rim D.

Having thus shown and described my invention so as to enable others to construct andutili'ze the same, what I claim as new and desire to secure by Letters-Patent of the United States is:

1. The combination in a wheel-rim for pneumatic tires,

of a metal tire having one edge thereof cut away, pointed studs in the cutaway edge of the. l'.i1'e, and a flange adapted to clamp the inner edge of the tire-sheath against the cut-away edge of the tire and the pointed studs therein, substantially as set forth.

2. The combination of a wheel-rim, a metal tire thereon having one edge thereof cut away, flanges removnhly bolt! cd to the sides of the wheel-rim, a'tire-sheuth rifted at its inner face and having the edges of the rift therein non annular circumference than the other. and pointed studs adapted to be pressed into the edge of the tire hythe pressure ex erted 0n the removable flanges, substantially as set forth. In testimony whereof I atfix my signature, in presence of two witnesses.
